The show begins with a woman named Beck (Elizabeth Lail) who walks into the bookstore Joe works in. As soon as we see her, we hear Joe's immediately obsessive inner commentary of her, and so the story of him stalking her and eventually dating her unfolds — but it's not without its obstacles. Joe goes to incredible lengths to make sure no one dates Beck but him, which includes — but is not limited to — murdering anyone who gets in his way.

If your teen has been expressing interest in watching the popular show or you have a feeling this might be the kind of series they'd click on if it came up on their Netflix homepage (which is exactly what happened to me, and once I hit "play," there was no looking back), there are a few things you should be aware of first. You know your teen best, but You is a heavy show with a lot going on, so read ahead to know what your teen is getting into before they start (and get hooked on) the series.
